I find that often after awakening from suspend on Ubuntu GNOME 16.04 with GNOME 3.20 (I have only found this issue on the latest version, though I have not tried with GNOME 3.18 on 16.04) that I get this strange font issue which can't be fixed by restarting gnome-shell and seemingly only by restarting my entire machine:

I do not believe that this is a theme issue as I have tried all the built-in themes (including the dark and light versions) and it is the same for them all. Though it does not seem to affect gnome-shell areas, that is the top-bar, the Activities Overview, etc, are not affected for some reason. So what could this issue be caused by and how can I fix or workaround it?

Information Update:

I have had a look at this answer but the only options in the gnome-tweak-tool for Antialiasing are Rgba, None, and Grayscale, but none of them seem to have any affect on the issue. Is there something I'm missing?

In 16.04 the Xorg config files are placed in /usr/share/X11/xorg.conf.d. Shouldn't this file be placed there too?

What does the LTS mean, if this fix wont come to 16.04? Such a major issue, and no fix yet to 16.04? Switching to 17.04 is the only solution. Shame on canonical!

@ashishsony The fix is available for 16.04. Just update to a 4.8.x kernel, which is available in official 16.04 repositories.

+1, except that I think the issue started being shipped from kernel 4.4.0 as many people reported in the referenced ticket, instead of 4.4.6. I'm having this issue with 4.4.0-96, on my 14.04 machine.

Then possibly there are more bugs with these symptomps? Thanks for the info, rewording.
